3 Why Alternative Fuels? Environmental Regulation By 2020, 10% of renewable energy should be incorporated into transportation sector (from renewable sources: biofuels, electricity, H 2, etc.) (2009/28/EC) Diesel pool challenges FAME incorporation limited to 7 % for diesel (EN590) Jet Fuel challenges Aviation integration into EU ETS (Emission Trading Scheme) Reduce Pressure on Petroleum Resources Crude oil reserves are limited Air traffic expected to double by 2020/25 Reduce Risk on Energy Security of Supply Reduce Carbon Footprint of Transportation Use short cycle carbon sources (i.e. biomass) Carbon free energy for transportation still to come 3

4 Alternative Fuels Challenges Preferred Alternative Fuels for Transportation are Hydrocarbon Liquids (density of energy, compatibility with existing fleets) Large alternative carbon sources are gaseous or solid (natural gas, coal, ligno-cellulosic biomass, waste) They are often containing much more than Carbon and Hydrogen (oxygen, impurities) 4

5 Mbdoe Axens Estimates Biojet + Biodiesel Source: Axens estimates (2011) Biodiesel contribution to on-road diesel supply ~ 5.1% by 2030 (2.3% today, ~ 4.5% by 2020) ~ 12% of incremental demand Biojet contribution to jet fuel supply ~ 6.5% by 2030 (0% today, ~ 1% by 2020) ~ 20% of incremental demand BtL 0.20 Mbdoe Biojet (HEFA) 0.43 Mbdoe Biodiesel (FAME + HEFA) 0.80 Mbdoe est est. BtL = Biodiesel from Biomass to Liquids ; FAME = Fatty Acid Methyl Ester ; HEFA = Hydroprocessed Esters and Fatty Acids 2020 est est est. 5
